I Tried Test-Driven Development for A Month and Survived

Test Driven Development

CodeSignal

When a candidate has made it past the initial screening process, we’d typically like to take a closer look at their work, so there’s less of a need for automated testing. In this episode we look at a type of task that assesses a candidate’s ability to write tests using a testing framework, and then use them to write and validate a corresponding algorithm. The candidate’s ability to write their tests in this case is just as important as their ability to write a solution.

Today there was an interesting discussion between Kent Beck , Martin Fowler , and David Heinemeier Hansson on the nature and use of Test-Driven Development (TDD), where one writes tests first and then writes code. ” Kent often (though not always) liked writing tests first so that he could observe their behavior while coding. It’s possible to minimize this point and say it’s only relevant to debugging or testing. Write a test (action).

When TDD Is Not a Good Fit

In both cases, had I started by writing tests, I would have wasted effort on writing tests for solutions that turned out to be wrong.
